The illustrated embodiment shows besides the perforating mechanism more or less diagrammatically the essential parts of a known electrical tabulating machine in which the cards are fed through the machine one by one and are analyzed by analyzing brushes which in turn control the printing and accumulating mechanisms of the machine in accordance with the perforations of the cards. The accumulator is engaged in a well known manner by means of electromagnets to the driving means and is then mechanically rotated by the same; the printing mechanism is reciprocating either horizontally or vertically and is provided with a number of type bars corresponding to the number of columns of the record card, one type bar being provided for each recording place. Said bars are upon item printing under the control of the cards or upon total printing under the control of the accumulator mechanism. Since the mechanical parts of such a machine are generally known and since such a machine is described in several patent letters (such as for instance in the United States Patent No. 1,600,413 and Reissue-Patent No. 16,304) the present speciflcation will refer only to the most essential parts and the general operation of the machine will be described in connection with the circuit diagram.

The accumulator mechanism is shown diagrammatically in Fig. 2 in which the accumulatorWvheel is indicated at .2; said wheel is driven by a wheel 82 which may be engaged by means of a coupling lever II with the continuously rotating driving shaft. The clutch lever II is electromagnetically controlled by the accumulator magnet 940 (Fig. 1) of the respective record column, and will be disengaged at the end of the card passage so that the amount represented by the perforation will have been entered into the accumulator wheel 82. Simultaneously with the accumulator wheel I! the cam wheel 84 isrotated by the driving wheel 82, the height of the steps of said cam wheel corresponding to the adjustment of the accumulator wheel 82. The cam wheel 84 is by means of contact devices 850, I (Fig. 3) which in turn control the printingmagnets "0 (Fig. 1) in accordance with the adjustment of the accumulator so that the respective total will be printed.

The printing mechanism may be under the control of the record cards for. item printing as well as imder the control of the aforesaid contactmechanism 850, "l for total printing. The printing mechanism for one place (correspondto one record column) is shown in Fig. 2. From this figure may be seen that a reciprocating lever 20 is connected by link 28! with a cross head 34 being movable along vertical bars II and receiving a vertical movement by the aforesaid lever 26. At the opposite end of the mechanism the cross head is also connected to trol of magnets a link 290 and lever 26 cross head 30 extend arms carrying a cross beam 32 passing through a number of slotted type bars 33; each type bar 33 carries on its head a number of type 34 being movable in vertical direction and corresponding to the ten numerals (L9. The bars 33 are normally drawn upwardly by spiral springs 350 which are connected to levers 360; the bars 33 are therefore held in engagement with the low the upward movement of the latter (which the same receives by levers 26) until they are arrested by pawls 3! which are under the con- 380, said pawls engaging into the notches "of the bars 33. The spacing of the notches 38 corresponds to the spacing of the movable type 34 and the movement of the bars 33 under the control of levers 16 is effected in synchronism with the passage of the record card under the analyzing brushes; if therefore the brush encounters a hole, the coordinated magnet 380 will be energized and thereby the bar 33 will be arrested at a point of its upward movement at which the type corresponding to the perforation is in printing position and the bar will be held there until printing has been effected.

The cross head 30 has rearwardly extending projections with rollers 40 engaging into slots of levers 4| which are pivotally mounted at 42; if the cross head rises, said levers will be moved rearwardly due to the shape of said slots and the cross beam 43 will therefore be moved to the left in engagement with the pivotally mounted spring actuated levers 44; the latter will be pressed rearwardly thus moving a number of spring actuated printing hammers 45!) away from the type. At the end of the upward movement of the cross head 30, however, the bar 43 will be drawn downwardly and escapes from the ends of the levers 44; since the same are then all simultaneously released they will be drawn by their springs in clockwise direction so that the printing hammers will impel the selected type against the platen 85. The type will therefore print upon the record sheet 48 the numeral corresponding to the perforation.

For the suppression of zero printing in the places to the left of the highest numeral place and for automatic zero printing in the places to the right therefrom, there is a zero controlling mechanism provided which is shown more in detail in Figs. 2 and 6. This controlling mechanism comprises a lever I20 for each type bar, said levers being pivotally mounted at I2l. Each lever has an arm I22 extending over the lever to the left thereof. If the lower ends of the levers I20 catch into a notch III of the bars 33 the bars are permitted to move upwardly to a point where an idle respectively. From the type is in printing position; however, if the levers,

I20 do not engage into said slots the type bars are arrested by a projection I24 in a position being for one unit lower and in this position the type bars will hold the zero type in printing position so that in all the respective places zeros will be printed. It will be seen that due to the superposition of the levers I 20 in all places being to the right of the highest numeral place, zeros will be automatically printed, in item as well as upon total printing, 1. e. independently of the control of the type bars by the record cards or by the accumulator in case there is no other numeral type adjusted, and that in places being to the left of the highest numeral place the type bars will be moved to the highest position since in said places the arms I22 are .permitted to move freely cross beam 32 and will fol-' then through line 69 to a,oos,es7 into the slots I23 so that in saidplaces no printing'will be eflected at all.

Since the perforating mechanism may be used at will in connection with the printing tabulating machine, at first the operation of the tabulating machine without perforating mechanism shall be described in connection with the circuit diagram and thereafter the perforating mechanism will be described as well as its operative connection with the parts of the tabulating machine.

By depression of the start key at 510 (Fig. 1) the current circuit will be closed from the main line through the tabulator motor TM, leading then over the clutch magnet 21, motor relay 90, start contact 510, motor control relay contacts 11, cam contact 305 (now being closed), cam contact I29 and contacts 550 to the other main line of the current source. If only 1mm printing is to be effected, the same current circuit as mentioned before will be closed with the only exception that the current will then flow from the cam contacts I29 through the contacts 520 and 540 to. the other main line, and the machine is operated at a lower speed. It is to be mentioned that the cam contacts BI, 62, 64 are all controlled in unison by means of shaft 39 which rotates synchronously with the other parts of the machine. The cam contacts 305 are controlled by shaft 220 rotating synchronously with the shaft 39. The came I540. for contact I29 is fast upon shaft 900 of the printing mechanism. Consequently, if only the accumulator mechanism is in operation and no item printing is effected, this shaft will be in rest position. It will only be operated upon total printing and resetting of the accumulators. The automatic group control mechanism comprises in the illustrated embodiment four group indicator contacts 48 and a contact 49b; another contact serves to control the control relay H and contact 48 serves to complete the current circuit if the accumulator is only to be used for group indicating without any automatic group control. The

first of. the last mentioned contacts energizes relay.

1| if all contacts are closed, the relay remaining then closed under the influence of a cam controlled contact 64 as will still be described.

Card feeding is initiated either automatically or manually by the start key 510 and the cards run one by one through the machine as soon as the clutch magnet 21 connects the card feeding mechanism with the drive of the machine. If the cards run one by one through the slot l3, l4 (Fig. 4) nothing will happen until the first card comes under the lower brushes B and closes by means of card lever l8 thecontacts l9 and 29 after the contacts l1 have been previously closed by the other card lever i5. If it is now assumed that only cards belonging all to the same group are running through the machine the controlling holes under the upper. and lower brushes will pass at the same time under said brushes. This will establish a current circuit from a lower brush 6 tothe contact block i l and the contact block l of the corresponding upper brush and from there to brush 5. The current circuit leads from the upper brush to the plug contact 10 of the plug board; for reasons of clarity the plug connections which are normally to be made are not shown in the diagram. The current may then flow through one of the control magnets 29 back to the current source; the energized control magnet will interrupt the contacts 35, 3'6 to take the spark from the brushes and simultaneously the contacts 38 will be closed which complete a part of the shunt circuit including the control relay II. The same operations will take place during the passage of the remaining cards at the brushes inserted into the group control circuit so that the shunt circuit will be completed. During the machine cycle the cam contacts 64 are instantaneously opened which, however, has no effect upon the relay ll since the current circuit 13 is still closed by" contacts 38 while in the other case the current circuit of the relay would be interrupted. The plug 303 may ,be inserted into any one of the contacts 394 in order to exclude -one or plurality of control circuits if less than the total number of the existing group control units are required. a

.At the end of the passage of the first card under the lower brushes the cam controlled contacts 839 will be closed, thereby causing a current impulse through the group indicator magnet 45 which releases a lever not shown in the drawingsv and permits a bar to open all contacts 48 as long as the card run through the machine is not interrupted so that said contacts will remain open. It is still to be mentioned that the group indicator contacts 48 are inserted betweenthe points 14 and I5 to prevent entering of group data of the following cards into the accumulator after the group number has once been entered into the accumulator from the first card.

From the foregoing will; be seen that the group controlling circuit remains closed as long as subsequent cards are in agreement and consequently the .machine will continue in its operations. If it is now assumed that the last card of a group has passed under the upper brushes and is about to come under the lower brushes, the first card of the following group will be under the upper brushes; since both cards are provided with different group numbers the aforesaid controlling circuit will be interrupted between the upper brushes 5 and block l0 thereby interrupting also the current circuit 59 and preventing energization of magnets 29. Consequently, the contact 38 and the current circuit I3 will remain open so that upon opening of contacts 64 the relay U will bedeenergized and will interrupt the current circuit of motor relay [6, thereby opening the contacts 11. These contacts shunted to the circuit 18 and are inserted in mere'tabulating operations (accumulating with-- out printing and total printing) over cam contacts 96| and upon total printing over cam contacts 19;- said contacts open at the end of the machine cycle and consequently the motor relay 80 and also clutch magnet 21 will be deenergized so that the machine will be stopped.

If total taking is to be effected manually, the switch I05 must be opened (as shown in the drawings) and the reset key 580 must be depressed. Then a current will flow from the current source 590 through contacts 550 (during tabulating operations) or contacts 540, 520 (upon item printing), then through contacts I29 now being closed, through the various lines to the reset key 589, the contacts l09a now closing, the clutch magnet controlled contacts 96, reset magnet B20, reset, motor 600 to the other main line and back to the current source. The cam contacts llllia, I05 and 530 are provided upon a shaft rotating synchronously with the shafts 39 and 220. The reset motor 600 causes printing of the total and resetting of the selected accumulators as is usual in tabulating machines.

After total taking and resetting has been initiated by the reset key 080, the current is taken over from the reset motor by arelay controlled magnet 020 short circuiting thereset key 500. After total taking and resetting the magnet 020 will be short circuited. The control 01 the printing and resetting motor is governed by contacts I00 being provided upon shaft 900 rotating once during the printing and resetting cycle. Said contacts open at the end of the printing and resetting cycle the current circuit to the motor 600 and prevent thereby further rotationo! the motor. The means for taking first the total and then resetting the accumulators are controlled by magnet 620 as is explained in prior patents. It must still be mentioned that the contacts 95 prevent printing and resetting while the tabulating motor TM is running and has energized the clutch magnet which opens the contacts 00.

If the total is to be taken automatically the switch I06 must be closed. Then the contacts I05 which initiate printing and resetting will be closed (just before the machine is stopped automatically under the control of the group controlling mechanism) and printing and resetting will then be effected in the above described way. The current circuit of the switch I06 leads over the contacts which are under the control of stop key 500; it said contacts are open total taking cannot be automatically initiated.

After a total has been taken either automatically or by key actuation, restarting of the machine i'or the next card group may be eflected either automatically or manually. For the manual release only the start key 510 must be depressed thereby initiating another machine cycle as has been described. In order to eflect an automatic restart of the machine, the total switch I00 must have been closed before. Another start circuit will be closed over said switch as follows: From the current source 590 through tabulating motor TM, clutch magnet 21, motor relay l0, switch I 30, cam contacts I20 being closed at the end of the printing and resetting cycle by cam I54, around motor relay 80, through the lowercard lever contact 20 (now being closed since there are cards in the machine), through motor relay controlled contacts 11 (now being closed) then either through cam contact 305 or interruptor contacts to the cam contacts I20 (now being closed), through one of the contacts 550 or 820-540 to the other side of the line and back to the current source. Said current circuit will automatically initiate another machine cycle.- The machine will then continue in its operations since the contacts of motor relay 00 remain closed until they are opened again at the end of the next card group under the influence of the automatic group control mechanism, whereupon total taking, resetting and restarting oi the machine may again be initiated in any one of the above described manners.

It the card supply is exhausted, accumulation of the data oi the last card will be completed in the known way and then total taking will be eiIected; this, however, needs no further explanation in connection with the present invention since the respective operations are described in the above mentioned prior patents. The cam contacts 000 serve to release the current impulse to the group indicator magnets at the proper moment in the machine cycle. The cam contacts I20 serve for the control 01' the current supply to the current circuits 22I leading to the total taking contacts 050 and 060 which are controlled in the known way by the cams 04; the

-the drive mechanism of the machine.

printing magnets 300 are in series with the contacts 000. I I In order to permit printing of the total from any of the accumulators at will, there are provided three contacts I00, I01 and I" which are controlled by levers I. It said contacts are open the printing current circuits oi. the coordinated accumulators will be interrupted thereby preventing totaltaking. If it is desirable to switch oi! simultaneously all total taking magnets, the switch 309 can be opened thereby interrupting the current circuit oi the cam contacts II. In the present embodiment the printing magnets are in series with the accumulator magnets 040 and if a controlling impulse is released both magnets will be energized simultaneously. The adjustment of the machine either .Ior item printing and accumulation or accumulation only may be controlled by a special lever which controls also This mechanism as well as further details, however, are clearly described in the prior patents so that no further explanation is necessary in the present specification' The switch 302 shown in the diagram serves to close a current circuit which prevents in any way automatic group control; this is desired it the machine shall only accumulate the data or ii. only item printing shall be eii'ected independently of the group designations of the cards.

The switches 3 l0 and 302 serve to permit tabulation if they are closed; if the switch 302 is closed the automatic group control mechanism is switched oif. If the switch 302 is open as illustrated and switch 0|. is closed, group control will be effected in the record columns coordinated to the accumulator as far as corresponding plug connections have been made.

In a printing tabulating machine the accumulator wheels control total taking while item printing is eflected by the record cards. The accumulator magnets 040 which are energized by the holes and which are adapted to eng e the ac-- cumulator wheels close a shunt circuit about the brushes over the contacts I". This is for a double purpose, on the one hand to take the spark from the lower brush 0, and on the other hand to maintain the current circuit through the accumulator magnet 940 and the printing magnet 300. I1 now the automatic group control shall be eiiected the same devices are used. By energization of magnets 900 the main current circuit of the brushes will be interrupted by contacts ill, and simultaneously the shunt circuit will be established through contacts Ill. Due to the interruption of the contacts II! back circuits through the holes of the upper card are prevented. Bell crank levers I04 are coordinated to the contacts I00, I01 and I30 for the selective control oi total printing from the various accumulators; said levers are under the control of the reset clutches as has been described in the above mentioned ,prior patents. If the reset clutch of any accumulator is moved to the left, resetting of the corresponding accumulator will be prevented by simultaneously opening the coordinated contacts I00, III! or I39, and accordingly also total taking from the respective accumulator which is not reset will be prevented. I! on the other hand the clutch member is adjusted in the right hand position, the accumulator will be reset and the corresponding switch will be closed so that also a total will be taken from said accumulator. In the generally known way provision may also be made to take a total without resetting the accumulator.

Now, reference will still be made to some. general operations of the is to be used only ior'mere accumulating (without printing any items) "the tabulator will operate in the usual way with a higher speed, and by means of a shiitable speed mechanism the contacts Bil-5 will be opened. lit the same time, the operator of the machine will open the switch I which prevents total printing. The machine may then operate as an ordinary computing machine and the printing mechanism will be idle during the accumulation. Upon resetting, the printing mechanism will periorm one cycle, but since the total taking circuits are not closed no printingwill be eilected.

Ii it is desirable to accumulate the data of each card group and to print the total of each group. the switch 309- must be closed so that total printing at the end of each card group will be permitted. During such accumulating operations, item printing will be entirely suppressed and during the printing operations only the total of the previously accumulated items and the co ordinated group number will be printed.

The above described manner of operation may be periormed either iullyor semi-automatically.

for instance the data 01' a stack of cards may be accumulated and ii the switch 302 for the automatic group control is open the accumulation will be automaticallyginterrupted ii the card group changes. .Total taking may "then be initiated manually by depressing the key 5 or automatically (ii the switch I06 has been previousiy closed). Alter total taking (either automatically or manually) the tabulating machine may be restarted either automatically or man- In the latter instance it is only necessary to depress'the start key 510 while in order to cause automatic restart the switch I30 must have been closed. It said switch is in closed position the initiation of another machine cycle will be automatically eflected bythe cam contact devices.

I! it is desirable to print items, the printing, mechanism is rendered operative through the printing ieveras hasbeen described in the prior Simultaneously therewith the speed corresponding contacts will be opened and this will cause operation oi the tabulator with a lower speed. It is then possible to print the various items and to accumulate the same as well as to print the respective totals. It will be seen that thegroup numbers serve iorthe control oi embodiment they are not entered into the accumulator from each card; the group number isprinted adjacent the first item and then no further printing will take place until the total is taken when. the group number will again be printed adjacent the total. The group number may, however, also be printed to each individindicator contacts analyzing circuit;

ual item, but then the group I8 are not iigrerted into the with this ma her will not be printed together with the total.

The perforating mechanism which is provided according to the present invention in the. tabulating machine, comprises a number oiperioration units, one unit being provided for each record column to be punched as is for instance shown machine: Ii the machine er of operation the group nun-- in Fig. 5. mama. s and 9 maybe at the one end (preferably at the left end) of printing roller 55 there is a groove provided said-roller in which a matrix block II is located; the latter is rigidly connected to a holder 51 in such a'eway that the inner stump oi the is permitted to revolve freely in the boring tween Ii and 51.

The matrix block ll has a hollow extending axially to theplaten over all rows punching stamps and terminating in apipe being preferably connected to an exhaus operated by a ventilator or the like in order to remove the waste from the space 52. Die pimclir carrier" comprises ior each record column (our resiliently mounted punching stamps it being symmetrically arranged above and below the plate 94 in the position shown in the drawings. The punching stamps 53 are slotted at their outer ends and into said slots engage pivotally mounted levers 95 being connected with slides II which extend through the guide plate 2501. the punching stamp case 24 to the outside of said plate. The distance of the slides 96 from each other corresponds exactly to the distance of the notches I! of the punching stamp carrier bar 33, 5|, 5! and the notches 39 in turn correspond exactly to the similar notches oi the type bar shown in Fig. 2. For the representation of a certain numeral the depressed by means of punching stamps 93 are the slides 98 either singly or in dliierent combinations in order to punch a hole combination in the record sheet 46. The selection or the mobing stamps is effected in accordance with the numeral to be punched in a similar wayas the selection of the printing type in Fig. 2. For each record column there is a notched bar 33 provided which is drawn upwardly by means oi spring 555 inasimilarwayasthetypebaroitheprinting mechanism in Fig. 2; each punch bar may be arrested in difierent positions by the pawl '51 under the control of the selector magnet II. The bar' 33' is connected with the bar 52 by a crow piece 5i and the bar 52 carries tour resiliently mounted pins 53 which are "spaced as shown in the drawings. If the bar 52, II is, in thelorwermost position, the uppermost pin 51 'is just for one tooth :19 below the lowermost slide 95, and ii 7 the bar 52 is in its uppermost position (the lowermost and uppermost positions are indicated by dotted lines) the lowermost pin 53 is tor one tooth is above the uppermost slide as. In all intermediate positions, however, one or a plurality of the pins 53 will be adjusted opposite the slides and if then in the way still to be described the plate 58 is moved to the right, the selectedpunching stamp or punching stamps ll respectively will be depressed under the control oi the pins 53 and the slides 96, through the record sheet t -and upon return movement of the plate 55 the punches will also return under the influence of their springs to their home position. The perwith the cams 66. .The

in connection foration scheme with respect to the various positions of the bar 33 may be clearly seen from Fig. 7 and may be verified in connection with Fig. 5; in Fig. 5 the punching bar is so adjusted that the numeral "6 will be punched, in accordance with Fig. 2 in which the type 6 is in printing pomtion. For reasons of clarity it is still to be mentioned that the hole positions pass in the sequence 9 to 0 under the brush and that consequently also the type and punching stamp bars must rise in the same sequence from the lowermost to the uppermost position through the various numerical positions. The adjustment of the selector bar 33' is effected by the selector magnet 66. During the machine cycle the type bars 36 (Fig. 2) and simultaneously therewith also the punching bars 33' are raised by the same mechanism which has been previously described. At the end of the machine cycle, and at the same moment in which in the printing mechanism the type hammers are impelled towards the record sheet, the peaks of two cams 66 iotating once during each machine cycle will encounterthe fingers 61 of a frame 66 being guided upon pins of the casing, said frame being normally held by springs 66 in engagement 7 peaks of the cams 66 will move the frame 56 and the pins 63 lying just opposite said frame to the right, and consequently also the slides 66 and levers 66 will be moved far enough to press the corresponding punching stamps 63 through the record sheet 46 while all other punching stamps, i. e. those punching stamps to which no pins 63 are coordinated between their slides 96 and the plate 66 will be inoperative and no perforation will becaused thereby. After perforation has been effected and printing has taken place in the previously described way, all parts will return to their home position and consequently also the punching bars 62, 33' will return under the influence of the cross head 30 to their home position.

Controlling of zero punching upon item perforation as well as upon perforation of a number under the control of the accumulator is effected (in a similar way as has been already explained with the type bar) by means of a pivotally mounted lever I26 encountering either in all places being to the right of the highest numerical place the zeros will be automatically punched while in all places to the left thereof the bars 62 will raise for one unit higher so that the lowermost pin 63 moves beyond the uppermost slide 96 and consequently no perforation will be effected at column. The distance of the perforation from the side edge of the record sheet determines the denominational value of said perforation, however, the meaning of the perforation is thereby not yet una uivocally determined. For purpose there is a special standard point punching stamp provided which produces, each time a record perforation is eifected, a hole on the same predetermined position which hole is invariably at the level of the lowermost hole position of the record perforation and which is therefore adapted to serve as a reference point for the meaning of the hole combinational records. The device for producing the standard point hole may be seen from Figs. 5 and 8. On'opposite side walls of the casing are two bell crank levers I66 (in the drawings is only shown the lever lying on the one side pivotally mounted which are connected with one another by a cross bar I6I which is normally all in the respective punching drawn by a spring I63 against the left edge of the bars 62. Each bar 62 has a recess 64 which is just opposite the yoke I6I if the 'bar 62 is in its uppermost position (1. position). The recesses 64 of all perforation bars 62 will therefore be Just opposite the yoke I6I if all bars 62 are in their uppermost position, i. e. if no record perforation will be effected at all. In this instance the spring I63 will draw the yoke I 6I into the recesses 64 and consequently the bell crank levers I66 will be rocked so that also (see Fig. 8) the arm I62 will be drawn downwardly and the arm I 64 connected therewith by a pin and slot connection will be moved downwardly. Said arm I64 as well as the arm I62 are, of course, to the left of the extreme left punching column; the arm I64 is pivotally connected with the punching plate 66 and lies normally opposite of a slide I66 adapted to cooperate with the standard point hole punching stamp I61.

The cams 66 rotate, of course, only during printing cycles so that only then a perforation will be effected provided the bars 62 are adjusted in punching position. If now for instance in connection with total taking no perforation shall be effected, the selector magnets 66 will not be energized and all bars 62 will rise to their uppermost position so that in each of such cycles the arm I64 (Fig. 8) is rocked lower than the slide I66; consequently, if the bars 62 are in their uppermost position there will be neither a record perforation nor a standard point hole perforation effected; however, if through one or a plurality of the bars 62 a record perforation is effected, the lever I66 is prevented to rock in clockwise direction so that simultaneously with each movement of the plate 66 to effect a record perforation also a standard point hole will be punched.

As will still be explained, with group accounts and printing of each individual item, the group designations are usually punched only to the first item of each group so that in such accounts the space required for the perforations needs no particular consideration since the printed entries upon said group accounts require in any way a longer record sheet than is required for the perforation. However, if only totals are to be printed or if a perforation shall be entered to each item, the record sheet must receive larger feed steps since the perforation requires a larger space in vertical direction than the printed line; The device serving for this purpose is shown in Fig. 10 showing the device adjusted for normal linewise type printing. The lever I66 having a projection I66 is raised synchronously with the printing mechanism, rocking thereby a lever III which is pivotally mounted at I63 and which engages with its pin I5I into a slot I 66 of a lever I46 pivotally mounted upon the shaft 66 of the printing platen and being normally drawn upwardly by a teeth of the ratchet wheel I41 fastened to the platen roller and being held in its position by the bell crank lever- I46..- If the lever I46 is of the arm I66 the pawl e. one step above the zero national system; it will,

- and will engage only serted immediately foration corresponding 2,008,453? "ever,'-the roller i45'wili slide upon the plate I48 far'erlough that the shift pawl will skip two teeth the third tooth thereby effecting a shift step corresponding only to the length of one tooth which corresponds just tozthe normal distance between. two printing lines. This adjustment of the record sheet feed mechanism is for instance used in connection with the above mentioned group accounts. However, if a perforation has to be effected to each printing line, the plate I48 is-adiusted in the position shown in Fig. 10 in dotted'lines and is secured by means" of the set screw I then be in engagement with the'ratchet wheel during the whole backward stroke of the lever I48 and consequently the pawl 'will rotate the platen for three teeth thereby effecting. a sufiicient distance between the various record lines and providinga suitable blank space between the various perforations coordinated to the printed lines.

Now the various manners of operation in connection with perforation shall be described on hand of the circuit diagram of Fig. i.

If it is desirable to punch to each item the identification represented in a certain hole field of the record card, such as for instance the account number, the selector magnets 68 are inbetween the plug contacts 14 and so that H the magnets are immediately in series with the accumulator magnets 940 and the printing magnets 388. The selector bars of the punching mechanism are locked in a mechanical way after instantaneous energization of the magnets 88 while the printing and accumulator magnets are included over the contact 3 l 1 into a shunt circuit. Since the records to be perforated are usually group indications or identification designations, total punching will usually not be effected; however, the total may be taken from the accumulators and punched in the above described way. In this instance, the selection and adjustment of the various switches of the tabulating machine must be effected in the known way for item printing so that the various items will be printed and a perforation will be entered to each item in the above described way, said perto the perforation of the record field selected for said purpose, with the onlydifference that the respective number is represented upon the card according to the single hole system while the perforation upon the record sheet is effected according the hole combiof course, be understood that the invention is independent of the system of perforation.

If group accounts are to be made by means of the automatic group control mechanism it may be desirable to punch the identification or group designation to the first item of each group but to suppress the perforation for .each following item of the same group. Further, it may be desirable to print to the first item (in addition to the perforation) the group other items, or to print said group number only to the first item. In the latter instance (i. e. if the group number is to be punched and printed only in connection with the first item) the magnets and the group indicator contacts 48 must be inserted between the plugs 14 and 15, the magnets 60 lying then in series with the contacts 48. After the passage of'the first card, the selector magnets 60 and the printing magnets are switched off from the analyzing brushes due to the interruption of the contacts 48, after no printing of the group .i4i. The pawl I44 will from the analyzing brushes,

\ group number under the number, as well as to all' the group number has accumulator by means of magnets 940. During printing of the following items/there will be number and also no perforation of the same, and only upon total taking the group number which has been entered into the accumulator will again be printed by the printing magnets but it will not be punched in the present instance. If it is desirable to print the group number to each item and to punch, however, said number only to the first item of each group,'the magnets 80 and contacts 48 are switched in series between the plug contacts 88 and 18. This will cause that after the passage of the first card due to the interruption of the group 68 will be switched off from the current circuit, and consequently no perforation can be efiected during the following items. Simultaneously with the aforesaid switch connection, however, also a direct connection must be made between the contacts 14 and I5 so that the, group numbers are entered each time into the printing mechanism and are printed to each item., Also in this instance the group number will normally not be prlntedtogether with the total.

. Another manner of operation consists therein that all items are only accumulated (but not printed) and then only of each group of items may be printed. In this instance it may be desirable that the group number be also punched to the total and, if desirable; thegroup number may also be printed. For this purpose the magnets 880 directly to-the plug contacts 98; the group indicator contacts 48 are switched between the plug contacts 14 and I5fso that the group number of the first card is entered into the accumulator and remains adjusted in the same. During the following accumulation of the data of the subsequent cards of a group, the printing mechanism will not be actuated, and if then upon total taking the printing magnets 880 are energized in accordance with the adjustment of the accumulator, the parallelly arranged selector magnets 80 will be energized simultaneously with the magnets controlling printing of the group indication so that the group number will be perforated as well as printed. If it should be desirable to punch the group number without printing the same it is only necessary to exclude the mag nets 380 and insert in place thereof the selector magnets 60. Punching of the group number in totalling operations It is also possible, machines, to print the immediate control of the first card and to punch the same, and then entering the total after completion of the group accumulation. If this manner of. operation is chosen it is only necessary to switch the magnets 60 and contacts 48 in series between the plugs 14 and 15.

By means of the above described machine, of course, group accounts of the described kind may also be made without printing the total to each group. For this purpose the group control mechanism is rendered operative and the total taking as in known tabulating switches are opened so that only the items of' been entered into the indicator contacts 48, the magnetsv is, of course, not restricted to the above described ways.

tion either only to the first item or to all items of the respective group.
